The "Nothing Breaks Like a Heart" singer posted a video Monday night of herself singing along to Lohan's 2004 hit song, "Rumors."
Cyrus has been Team Lohan all the way lately, and even defended LiLo's MTV reality show, "Lindsay Lohan's Beach Club," as the "best show ever."
Lohan has also taken notice of her famous fan, and shouted out the new Mrs. Hemsworth for showing love. The paralleled lives of the two stars can't be ignored -- child stars who both went through wild phases and seem to have leveled out as they matured.
This may be the collaboration we never knew we needed to see!
